Use the condition before download the file Response.IsClientConnected -

if (Response.IsClientConnected)
 {
    Response.Clear();
    Response.ClearContent();
    Response.ClearHeaders();
    Response.ContentType = "Application/pdf";
    Response.AppendHeader("Content-Disposition", "attachment; filename=" + fileName);
    Response.TransmitFile(Server.MapPath(@"yourpath" + fileName));
    Response.Flush();
    Response.Close();
  }
